Drucker's personal history?

his Primatech Assignment Tracker File is saying to check the archives. I'm assuming that it means the Corinthian Hotel's archives b/c that's where Hana's conversation with Micah led me. the problem is i can't figure out the entrance code. i can't figure out what micah means by "Twelfth". is getting in the archives a hacker thing, a riddle/puzzle, or am i thinking to hard? i know this is from awhile ago, but i recently just stumbled across this stuff and it has me interested and also stumped. any help would be appreciated.
